System Overview
The Atlas Copco's Industrial Location Guidance (ILG) is an integrated, stand-alone error proofing system that offers high-level process security for applications ranging from simple to complex.
ILG tracks the exact location of the tool relative to the fastening position, ensuring the correct fasteners are tightened to specification, in the proper sequence. Comprised of ILG software, positioning hardware (ILS Sensor) and tightening controller, the system combines the functionality of a tightening system with position and process control.
Monitors the location of the tool in the working area.
Guides the operator through the correct work sequence.
Automatically selects the tightening parameters for the position.
Ensures the correct fasteners are tightened to specification.
Unique P-Set selection for each position for full traceability.
The positioning hardware includes high precision rotary or linear position sensors that are integrated into the pivot joints or linear guides of a torque arm or similar applications. The sensors interface with the tightening controller or the Industrial PC via a gateway module. The gateway module communicates with the ILG service using Modbus TCP protocol. The ILG service communicates with the tightening controller through Open Protocol. Multiple Atlas Copco tightening controller models are compatible with the system and various positioning hardware configurations are available to suit the different arm types.
An ILG system consists of:
ILG software
Positioning hardware
Tightening controller
Industrial PC (optional /dependent on application)
The ILG service receives the data from the positioning hardware sensors to calculate the tool location in three-dimensional space, in real time. Once the tool is located in the specified position, the ILG service will select the tightening program (P-Set) and enable the tool through Open Protocol. Visual indicators, through a Stacklight, tool LEDs, or the HMI process screen, will alert the operator to initiate the tool start.
ILS Sensor
The ILS Sensor is a is a high-level, wireless line of site error proofing process security system and it consists of a sensor and a tag reflector.
The Receiver triangulates real-time position of the tool tag when visible within the coverage area and the sensor calculates the tag matrix position and generates (X,Y,Z) and (P,Y,R) location data values for the tag location. The tracking module sends information to ILG Software.
The ILG software validates the position and is used to enable or disable tool. Using Open protocol, it is provides position error proofing for bolt/process level operations.
